Using the world’s smallest commercially available steel ball bearing, MinebeaMitsumi Inc. has built the world’s smallest fidgetsSpinner. In measuring just 5.09 mm (0.20 in) long, a system capable of measuring the device accurately is required. This is where the NEXIV VMR-3020 comes in. The high precision system is designed for superior edge detection, even in transparent materials. This is crucial for accurately measuring such small items with tight tolerances.
